Abstract
1531602 Mechanical switches AMP Inc 3 June 1976 [20 June 1975] 22881/76 Heading H1N A rotatable switch operating member 25, having a cam 29, 30 for separating a pair of contact springs 16 having terminal posts 18, is mounted in an insulating housing 9 by engagement with at least one of the springs 16. Each spring 16 comprises a tin-plated copper alloy strip received as an interference fit in an aperture in the housing 9 and secured in place by a tab 19<SP>1</SP> bent into a recess 31 at the bottom of the housing 9. One end of each spring 16 has a tab 21 with an upwardly bent free end 23 which is biased into engagement with a downwardly bent free end 24 of a tab on the other terminal 16. The operating member 25 is held in a socket 14 in the housing 9 by a horizontal portion 22 of each tab 21 and by a further tab 20 on each spring 16 which engage the end of the cam portion 29, 30. The posts 18 can be plugged into a printed circuit board.
